The essay Of Dwarves and Men in volume 12 of The History of Middle-earth mentions that the Dwarf-cities of Nogrod and Belegost were occupied by the Firebeard and Broadbeam clans. That source is not specific about which division of the Dwarves lived in which city, but based on the order of words used, the Dwarves of Belegost most likely derived from the Broadbeam line.
